Ten weeks of research may not be everyone’s idea of the best way to spend a summer. But the students who participated in the first undergraduate summer internship program sponsored by the Johns Hopkins University Institute for NanoBioTechnology will tell you it was a summer well spent.

INBT awarded a total of $35,000 to support the work of 10 students pursuing original projects in the labs of Johns Hopkins University and INBT affiliated faculty. The results of their findings were displayed during an Aug. 10 poster session at the Homewood campus. Posters were judged by INBT affiliated faculty and others who attended the gathering.

“It was a great experience spending time with the postdoctoral students and faculty members because during the school year I would not have had time to work with them so closely,“ says Fan Yang, who will be a senior in materials science this September.

Yang’s poster, “Pancreatic carcinoma imaging using fluorescent dye doped nanoparticles“ -research she completed with INBT faculty affiliates Professor Howard Katz (Materials Science and Engineering) and Professor Ellen Silbergeld (Environmental Health Sciences)—tied for best poster overall with Brady Sieber, this fall a senior in public health studies. Sieber worked with perflurocarbons to enhance the viability of encapsulated mesenchymal stem cells.

“It was exciting working with stem cells,“ Sieber says. “I learned that things like this take a little longer than you would think because there are always things along the way that you don’t expect to happen. You just have to keep trying new approaches, and hopefully you will get results that will be what you wanted.“ Sieber’s work was supervised by INBT affiliated faculty members Associate Professor Dara Kraitchman (Radiology) and Professor Jeff Bulte (Radiology).

Chih-Ping Mao, this fall a junior in biology, worked with INBT affiliated faculty member Assistant Professor Chien-Fu Hung (School of Medicine). Hung says, “The INBT interns were very talented; I was very happy to work with them,“ Hung says. “They learned very quickly, worked hard and participated in all aspects of research. I was quite impressed.“

In order to be considered for an internship, students were required to have experience in the development and use of advanced nano-materials and structures and techniques for nano-fabrication with an ultimate goal to solve important problems in biology, health and the environment and medicine. A review committee, made up of Hopkins faculty affiliated with INBT, received about 50 submissions from students in the Krieger School of Arts and Sciences, the Whiting School of Engineering, and the School of Medicine.

“The program was established to give undergraduates the opportunity to experience what it is like to conduct real scientific research,“ says Sue Porterfield, INBT administrative manager. “Next summer, we will be able to expand the program through funding from the National Science Foundation.“
